Title: Acetabular cup
Inventor: SWARTS DALE F
IPC: A61F2/34
Filed: 1996-01-31
Granted: 2007-01-16
Abstract: The present invention is directed to an acetabular cup prosthesis for implantation into a pelvic bone. A cup having a cavity for receiving a femoral head is formed of a polymeric material having a predetermined tensile strength. A backing is disposed about and attached to the polymeric cup. The backing has a porous construction defining interstitial pores, with the pores being sized to receive a portion of the polymeric cup therein and adapted for allowing ingrowth of the bone therein.

Patent CA-2179668-C (CA)
Inventor: JOHNSON LIANN M
IPC: A61F2/966
Filed: 1993-03-10
Granted: 1999-07-20
Abstract: A radially self-expanding stent particularly suited for treating esophageal strictures, includes a medial region and proximal and distal cuffs having diameters greater than the medial region diameter when the stent is in the relaxed state.  A silicone coating circumscribes the medial region, but the cuffs are not coated and retain their open weave construction.  As a result, the cuffs remain particularly well suited to immediately contact esophageal wall tissue and resist stent migration, while the silicone coated medial region provides a barrier to tumor ingrowth, and has an enhanced radial restoring force to maintain an open passage-way in the esophagus.  A deployment device for the stent includes an interior catheter surrounded by the stent and having an esophageal dilation feature, along with an exterior catheter that radially compresses the stent. A low durometer sleeve, fixed to the interior tube and in surface engagement with the compressed stent, tends to fix the axial position of the stent relative to the interior catheter whenever the exterior catheter is moved axially relative to the inner catheter. Consequently, precision in stent placement and the ability to recapture a partially deployed stent are enhanced.

Abstract: Comprising one or more resonant cavities in which are produced two resonant modes at two different frequencies f1 and f2, both modes having essentially the same field distributions but rotated 90 ° with respect to each other.      Each cavity comprises a tuning element (TS a) for tuning the resonant frequency f1 of the first mode along a first axis, a tuning element (TS b) for tuning the resonant frequency f2 of the second mode along a second axis perpendicular to the first, input coupling means (IC) and output coupling means (OC) for injecting into and extracting from the cavity, respectively, a radiofrequency signal along axes not parallel to those of resonance.      Filter tuning is done by using only two tuning elements, which means that the filter cost is lower and the tuning time is reduced.

Patent CA-2232202-C (CA)
Inventor: HASEGAWA TOSHIYA
IPC: B60G3/18
Filed: 1998-03-16
Granted: 2006-01-10
Abstract: In a wheel suspension system, a trailing link, which connects a knuckle rotatably carrying a wheel to a vehicle body, has a front end which is pivotally attached to a vehicle body via a coupling rod fitted with a rubber bush, an axial center line of the coupling rod is slanted so that a rear end thereof is offset toward a center of the vehicle body, and a rear end which is attached to the vehicle body via a lateral arm made of a plate member so as to be flexible in a fore-and-aft direction. Thus, when the rear wheel is pulled backward as a result of applying a brake, the lateral member made of a plate member deflects and the rubber bush fitted on the coupling rod connecting the front end of the trailing link to the vehicle body deforms in the axial direction. Because the axial line of the coupling rod is slanted in such a manner that the rear end of the axial line is offset toward the center of the vehicle body, as the front end of the trailing link shifts rearward, it shifts toward the center of the vehicle.      Thus, a desired change in the toe-in angle is produced when a brake is applied without compromising the firmness of the steering system.

Filed: 1997-10-23
Granted: 2001-07-03
Abstract: An apparatus and a method for coating zinc on steel sheets for use on automobiles and electronic apparatuses are disclosed. A fluidized bed forming chamber is provided to fluidize zinc powders in carrying out a zinc coating on a heated steel sheet, so that not only a uniformly coated layer but also a thick coated layer can be obtained. The apparatus for continuously coating zinc on a steel sheet according to the present invention includes a zinc coating chamber (220) for forming a fluidized bed of zinc powders, for passing a heated steel sheet (201) through the fluidized bed of the zinc powders, and for making the zinc powders melt-adhere on the steel sheet during its passing through the fluidized bed. A fluidized bed forming chamber forms a fluidized bed of the zinc powders by making the zinc powders suspended by spouting a gas. A cyclone (250) separates the zinc powders from the gas after recovery of them from the zinc coating chamber (220), to discharge the gas, and to return the separated zinc powders to the fluidized bed forming chamber (240). A  deflector shifts (211) the advancing direction of the steel sheet after its admittance into the zinc coating chamber (120). A tension roll (232) shifts the advancing direction of a zinc coated steel sheet. Further, the zinc coating chamber includes one or more electrodes for electrostatically charging the zinc powders.
